  Modified files:
    sys/dev/netif/bce    if_bce.c if_bcereg.h 
  Log:
  - Add tunables and sysctl nodes for interrupt moderation variables.
    Settings are committed to device during device initialization or in
    interrupt routine.
  - Default interrupt moderation variables' value from Broadcom's driver
    seem to be misconfigiured.  Following changes are made:
    Send max coalesced BD count		20 -> 24
    Send coalescing ticks			80 -> 1000 (~1000HZ)
    Receive max coalesced BD count	6  -> 24
    Receive coalescing ticks		18 -> 125  (~8000Hz)
    Two changes on "Receive" interrupt moderation variables avoid livelock
